Learning real-time search, which interleaves planning and acting, allows agents to learn from multiple trials and respond quickly. Such algorithms require no prior knowledge of the environment and can be deployed without pre-processing. We introduce Prioritized-LRTA* (P-LRTA*), a learning real-time search algorithm based on Prioritized Sweeping. P-LRTA*(More)
BACKGROUND Umbilical cord blood is an alternative peripheral blood progenitor cell source for patients who need transplantation. A presumed advantage of cord blood is the ability to increase minority recruitment. STUDY DESIGN AND METHODS The racial composition of five member cord blood banks of the National Marrow Donor Program (NMDP) was compared,(More)
In vitro and in vivo studies implicate occludin in the regulation of paracellular macromolecular flux at steady state and in response to tumor necrosis factor (TNF). To define the roles of occludin in these processes, we established intestinal epithelia with stable occludin knockdown. Knockdown monolayers had markedly enhanced tight junction permeability to(More)
In this report we describe a uniquely decentralized event-based system for online and offline tracking, analysis, and control of electronic document transactions in order to detect suspected insider misuse of those documents. Our system is focused on the problem of tracking and analyzing user's actions with respect to documents. On the user side, the(More)
The purpose of our study was to more fully investigate a combination of personal resources, namely positive affect (PA) and conscientiousness, on emotional exhaustion, depersonalization, and job tension. We examined a sample of nurses employed by a metropolitan hospital and found that the combination of high positive affect and high levels of(More)
BACKGROUND Detecting serum antibody against inhaled antigens is an important diagnostic adjunct for hypersensitivity pneumonitis (HP). We sought to validate a quantitative fluorimetric assay testing serum from bird fanciers. METHODS Antibody activity was assessed in bird fanciers and control subjects using various avian antigens and serological methods,(More)
Multiple myeloma (MM) is an incurable hematological malignancy with an average survival of 3 years with conventional therapy. Allogeneic hematopoietic cell transplantation (allo-HCT) may cure some patients, but has been associated with a very high transplantation-related mortality (TRM) of over 40%.(1) In contrast to allo-HCT, autologous hematopoietic cell(More)
Smokers with asthma have poor symptom control, accelerated decline in lung function and an attenuated response to corticosteroids compared to nonsmokers with asthma [1]. There is an unmet need for alternative or additional drugs for smokers with asthma who are unable to stop smoking [2]. Macrolide antibiotics have anti-inflammatory activity [3] and in(More)
